IMPROVEMENT IN MOTIVE POWERS.

Specification forming part of Letters Patent No. 154,919, dated September 8, 1874; application filed August 26, 1874.

' useful improvements in apparatus or motors for driving machinery of various kinds, or for operating churns, pumps, and other similar apparatus, in which a reciprocating motion is required; audit consists o f a double train of multiplyingggearing driven in opposite directions by means of weights, and imparting motion to a driving-shaft provided with a ilywheel and a crank, which gives an oscillating motion to a rock shaft or lever, which imparts the proper reciprocating motion to the dasherrod, piston-rod, &c., of the churn, pump, or other apparatus.

l In the drawings, Figure 1 is a front elevation of my improvement, and Fig. 2 an end view of the same.

A represents a frame, of metal or other material, of suitable strength, and B B the double train of multiplying gearing, consisting of two sets of gear-wheels, each set consisting of three large wheels, b bb, and two small wheels, b b', Amounted on the shafts C O O and geared together, as shown, in the manner of ordinary clock-work. Between the upper wheels of the double train I arrange a driving-shaft, D, cary rying a gear-wheel, H, and ily-wheel I. The front end of said shaft projects through the frame A, and is provided with a crank, K, as shown in Fig. 1. The crank-pin on said crank works loosely in a slidingl block, L, which travels in a slot -in the end of the oscillating lever M, which is secured to the frame A at one side by means of a pin, N, upon which it works. The other end of said lever carries an oscillating ring or socket, O, by means of which the piston-rod, dasher-rod, Sac., may be attached to said lever, said ring being provided with a set-screw for the purpose. The lower shaft of each train carries a barrel or drum, P, to which is attached a weight, Q, by means of a suitable cord, R, and the central shaft of each train, projects through theback of the frame A, and is squared, as shown, so that a key may be secured thereon .for the purpose of winding. The said shaft, in each train, is attached loosely to the large wheel thereon, and is provided with the usual pawl and ratchet wheel for carrying the wheel forward, and allowing the weights to be wound without moving the whole train inthe same manner as in ordinary clock-gearing. These .ratchets are so arranged that the trains or sets will be wound in opposite directions, so that the proper motion will be given to the upper wheel in each set to drive the drivingshaft of the apparatus.

The operation of my apparatus will be readily understood.

Upon winding up my apparatus the lower wheels of the double trains will be put in motion, imparting motion in turn to the rest of the gearing. The upper wheels will travel much faster than the lower nwheels, giving a rapid motion to the driving-shaft and oscillating lever without running the weights down too rapidly. rIhe two sets of thedouble train working together double the power of the machine, as will be evident.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The drivingshaft D, ily-wheel I, crank K,

and wheel H, in combination with' the sliding block L, slotted oscillating lever M, swinging ring or socket O, and double-train of multiplying-gearing, all constructed and operating substantially as described, for the purpose specied.

In testimony that I claim the foregoing I have hereunto .set my hand.

GEORGE I. SLATER.
